摘要：
An apparatus includes a drum to draw in or let out a line and a motor coupled to the drum to apply a torque thereto. The drum includes a groove formed in an outer surface thereof to accommodate the line. A roller is provided that tracks the groove and extends into the groove. The roller pushes the line into the groove. In certain embodiments, the roller pushes the line to a bottom of the groove to ensure that the line is properly seated therein.
